Bad Service

I used TNT as my courier to ship machine spare parts from India. The goods were duly collected from my supplier on the 28/07/2015, and arrived in JHB on 30/07/2015. As of today 13/08/2015 the goods are still with Customs in JHB. The tracking updates just repeat themselves, and the call centre are helpless. They DO NOT return calls, and REFUSE to give the contact details of their manager?<br> So Mark Anthony (manager) has been given my number and asked to call me. I won't hold my breath.
